SaaS Metrics & Unit Economics Calculator

Calculate every metric a SaaS business needs to understand its health, growth trajectory, and unit economics. Not a dashboard — a calculation engine that shows its work, flags problems, and tells you what the numbers actually mean.

Give it your revenue data, customer counts, and spend figures. Get back a full metrics report with MRR, ARR, growth rates, churn analysis, LTV, CAC, LTV:CAC ratio, payback period, burn rate, runway, magic number, Rule of 40, and net revenue retention — all with formulas shown so you can verify every number.

Capabilities:

• Revenue metrics: MRR, ARR, Net New MRR breakdown, growth rates (MoM, CMGR)
• Customer metrics: Logo churn, revenue churn, net churn, cohort retention analysis
• Unit economics: CAC (blended and per-channel), LTV (gross margin adjusted), LTV:CAC ratio, payback period
• Operational metrics: Burn rate, runway, magic number, Rule of 40
• Net Revenue Retention (NRR) — the single most important SaaS metric for investors
• Revenue forecasting with conservative, base, and optimistic scenarios
• Fundraising readiness evaluation against Series A/B benchmarks
• Benchmark comparison by stage (Seed through Growth) and segment (Consumer through Enterprise)
• Flags common mistakes: one-time revenue in MRR, ignoring gross margin in LTV, monthly vs annual churn confusion

Includes a complete benchmark database by company stage and customer segment, so you know where you stand relative to industry standards.

Every calculation shows the formula used. Every metric includes a health indicator and benchmark comparison. Every report ends with prioritized recommendations based on your weakest metrics.

Built for founders, operators, and finance teams at SaaS companies. No API keys or external services required — pure calculation and analysis.
